United States Patent 9 Claims (Cl. 167-33) This application is a continuation-in-part of applica tion Ser. No. 290,308, filed June 25, 1963, now .U.S. Patent 3,255,181, issued June 7, 1966-.

This invention relates to a novel method of controlling the growth of fungi by applying to the fungi or the substrate on which they grow, certain heterocyclic amines possessing fungicidal activity, or compositions containing these amines as active ingredients. The invention also relates to the said compositions.

For these distributed form as such or combined with suitable carriers and distributing agents. They can also be used in combination with other fungicidally active substances as well as with fungistatica and bacteriostatica. To increase the range of action, also insecticidally or nematocidally active substances etc. can be added to the active substances used according to the invention.

To produce fungicidal agents according to the invention the active substances can be mixed, for example, with solid, pulverulent carriers such as, e.g., talcum, kaolin, loess, chalk or ground limestone. If desired, the pulverulent agents obtained can be made suspendable in water by the addition of suitable wetting and dispersing agents such as sulphite waste liquor. In addition, the active substances as such in solid, finely ground form, can be suspended in water with the aid of capillary active substances, or they can be emulsified in water, after dissolving them in organic solvents, with the aid of suitable emulsifying agents. Also, the active substances can be dissolved in organic solvents, e.g., in chlorinated hydrocarbons such as trichloroethylene, or in medium petroleum fractions, boiling range 100 to 200 possibly with the addition of auxiliary solvents such as acetone or higher ketones, e.g., cyclohexanone. Finally, the active substances can also be employed in the form of aerosols, smoke or mist, particularly in storerooms and greenhouses.

The fungicidal active substances are applied to an organic material to be protected generally either by admixture therewith, by spraying or by impregnating with organic-aqueous or aqueous solutions of the active substance which can contain the active substance in dispersion or suspension.

The following examples further illustrate the production of some fungicidal agents:

EXAMPLE I 20 parts of 4-tert.butyl-7-myristylamino-3,4,5,6-tetrahydro-2H-azepine produced as described in Example 28 are finely milled in a ball mill with 4 parts of a polyvinyl pyrrolidone dispersing agent and 76 parts of water. The paste so obtained is suspended in water and is used for the combatting of fungi, particularly in orchards.

EXAMPLE II 50 parts of 7-n-octylamino-3,4,5,6-tetrahydro-2H-azepine, produced as in Example 7, 2 parts of an adhesive having a polyvinyl alcohol base, 10 parts of sulphite waste liquor, 16 parts of champagne chalk, 20 parts of kaolin and 2 parts of a wetting agent having an alkyl and aryl sulphonate base are milled together, mixed, and again milled. A 50% wettable powder is obtained which can be suspended in water and is suitable in particular for use in fruit cultivation.

EXAMPLE III 10 parts 7-octylhydrazino-3,4,5,6-tetrahydro-2H-azepine, produced as described in Example 12 are dissolved in parts of dimethyl formamide and 10 parts of an alkylaryl sulphonate are mixed into this solution until homogeneity is attained. In this way an emulsifiable solution is obtained which can be diluted to any concentration desired.

EXAMPLE IV 10 parts 9-n-dodecylamino-3,4,5,6,7,8-hexahydro-2H- azonine, produced as described in Example 38, are dissolved in 15 parts of dimethyl sulphoxides and 65 parts of cyclohexanone. 10 parts of an alkylaryl polyethylene oxide (ratio 1:10) are mixed into this solution until homogeneity is attained. An emulsifiable solution is obtained which can be diluted to any concentration desired.
